The correct order for the steps involved in DNA replication is:

• DNA unzips; DNA re-zips: bases match-up; 2 identical strands are made
• Bases match up; 2 identical strands are made; DNA unzips: DNA re-zips
• 2 identical strands are made; DNA re-zips: bases match up; DNA unzips
• DNA unzips; bases match up; DNA re-zips; 2 identical strands are made

Which enzyme “un-zips” DNA?

• DNA polymerase
• DNA Ligase
• Amylase
• Helicase
